Integrated measuring device and method for algae population biomass in lake and reservoir shallow-water areas

Abstract

The invention discloses an integrated measuring device for algae population biomass in lake and reservoir shallow-water areas. The device comprises a working panel which is arranged on a water surface, an underwater working box, an operating assembly, power assemblies, a measuring assembly and an identifying assembly, wherein the operating assembly is arranged on the working panel; the power assemblies are arranged in the working panel and the underwater working box; the measuring assembly which is measuring an algae content and the identifying assembly which is used for measuring an algae species are arranged in the underwater working box; the power assemblies, the measuring assembly and the identifying assembly are controlled by virtue of the operating assembly; the measuring assembly and the identifying assembly are driven to move by virtue of the power assemblies; and by virtue of the measuring assembly and the identifying assembly, measured data is returned to the operating assembly. The device provided by he invention, by virtue of magnetic algae and rotary settlement technologies, can achieve real-time vertical measurement of the algae population biomass in the lake and reservoir shallow-water areas, so that the algae biomass in the water areas as well as the constitution and proportions of an algae population can be accurately and continuously acquired in real time; and meanwhile, the vertical distribution of algae in water can be measured by virtue of the device which vertically moves in the water, so that a new way is created for the in-situ vertical measurement of the algae biomass in the water.

Description

technical field [0001] The invention belongs to the technical field of water environment protection, and relates to an integrated measurement device and method for algae population biomass in shallow water areas of lakes and reservoirs. Background technique [0002] The water bodies of inland lakes and reservoirs are relatively closed, which is prone to trophic problems, which will lead to a large number of plankton to form algal blooms and destroy the ecological balance of the original water bodies. Accurate and efficient monitoring of changes in algal populations and biomass is a prerequisite for effective prevention and control of eutrophication and algal blooms in lakes and reservoirs. The traditional measurement technology mainly relies on the manual detection method to analyze the composition of the algae population in the water body and estimate its number by manually operating the indoor measuring instrument, which has the disadvantages of high intensity, low efficie...

Problems solved by technology

Common large-scale algae monitoring technologies such as remote sensing can only measure the number of algae in surface water bodies, and cannot be directly used for real-time monitoring of the vertical distribution of algae cells in water areas
